基于sparksql调用shell脚本运行SQL，sparksql提供了类似hive中的 -e  , -f ,-i的选项

1、定时调用脚本

#!/bin/sh
# upload logs to hdfs  yesterday=`date --date='1 days ago' +%Y%m%d`  /opt/modules/spark/bin/spark-sql -i /opt/bin/spark_opt/init.sql --master spark://10.130.2.20:7077 --executor-memory 6g --total-executor-cores 45 --conf spark.ui.port=4075   -e "\
insert overwrite table st.stock_realtime_analysis PARTITION (DTYPE='01' )select t1.stockId as stockId,t1.url as url,t1.clickcnt as clickcnt,0,round((t1.clickcnt / (case when t2.clickcntyesday is null then   0 else t2.clickcntyesday end) - 1) * 100, 2) as LPcnt,'01' as type,t1.analysis_date as analysis_date,t1.analysis_time as analysis_timefrom (select stock_code stockId,concat('http://stockdata.stock.hexun.com/', stock_code,'.shtml') url,count(1) clickcnt,substr(from_unixtime(unix_timestamp(),'yyyy-MM-dd HH:mm:ss'),1,10) analysis_date,substr(from_unixtime(unix_timestamp(),'yyyy-MM-dd HH:mm:ss'),12,8) analysis_timefrom dms.tracklog_5minwhere stock_type = 'STOCK'and day =substr(from_unixtime(unix_timestamp(), 'yyyyMMdd'), 1, 8)group by stock_codeorder by clickcnt desc limit 20) t1left join (select stock_code stockId, count(1) clickcntyesdayfrom dms.tracklog_5min awhere stock_type = 'STOCK'and substr(datetime, 1, 10) = date_sub(from_unixtime(unix_timestamp(),'yyyy-MM-dd HH:mm:ss'),1)and substr(datetime, 12, 5) <substr(from_unixtime(unix_timestamp(),'yyyy-MM-dd HH:mm:ss'), 12, 5)and day = '${yesterday}'group by stock_code) t2on t1.stockId = t2.stockId;"\sqoop export  --connect jdbc:mysql://10.130.2.245:3306/charts   --username guojinlian  --password Abcd1234  --table stock_realtime_analysis  --fields-terminated-by '\001' --columns "stockid,url,clickcnt,splycnt,lpcnt,type" --export-dir /dw/st/stock_realtime_analysis/dtype=01; 

init.sql内容为载入udf:

add jar /opt/bin/UDF/hive-udf.jar;
create temporary function udtf_stockidxfund as 'com.hexun.hive.udf.stock.UDTFStockIdxFund';
create temporary function udf_getbfhourstime as 'com.hexun.hive.udf.time.UDFGetBfHoursTime';
create temporary function udf_getbfhourstime2 as 'com.hexun.hive.udf.time.UDFGetBfHoursTime2';
create temporary function udf_stockidxfund as 'com.hexun.hive.udf.stock.UDFStockIdxFund';
create temporary function udf_md5 as 'com.hexun.hive.udf.common.HashMD5UDF';
create temporary function udf_murhash as 'com.hexun.hive.udf.common.HashMurUDF';
create temporary function udf_url as 'com.hexun.hive.udf.url.UDFUrl';
create temporary function url_host as 'com.hexun.hive.udf.url.UDFHost';
create temporary function udf_ip as 'com.hexun.hive.udf.url.UDFIP';
create temporary function udf_site as 'com.hexun.hive.udf.url.UDFSite';
create temporary function udf_UrlDecode as 'com.hexun.hive.udf.url.UDFUrlDecode';
create temporary function udtf_url as 'com.hexun.hive.udf.url.UDTFUrl';
create temporary function udf_ua as 'com.hexun.hive.udf.useragent.UDFUA';
create temporary function udf_ssh as 'com.hexun.hive.udf.useragent.UDFSSH';
create temporary function udtf_ua as 'com.hexun.hive.udf.useragent.UDTFUA';
create temporary function udf_kw as 'com.hexun.hive.udf.url.UDFKW';
create temporary function udf_chdecode as 'com.hexun.hive.udf.url.UDFChDecode';

设置ui的port

--conf spark.ui.port=4075 

默觉得4040，会与其它正在跑的任务冲突，这里改动为4075

设定任务使用的内存与CPU资源

--executor-memory 6g --total-executor-cores 45

原来的语句是用hive -e 运行的，改动为spark后速度大加快了。

原来为15min，提升速度后为 45s.
